Question

What is an "alternate form of a gene"? a. allele b. gamete c. chromosome d. homologous chromosome Let's say we mate a plant with red flowers with a plant with white flowers. All of the offspring have pink flowers. This would be an example of ______. a. complete dominance b. co-dominance c. incomplete dominance d. hybrid dominance What potential gametes could an individual that is heterozygous for flower color produce? a. C and c b. CC and Cc c. only c d. only C Why can we observe phenotypes but not genotypes? a. the genotype is the expression of the phenotype b. the phenotype is the expression of the genotype c. the phenotype is only inherited from dominant alleles d. the genotype is only inherited from dominant alleles Homologous chromosomes ________. a. share a centromere b. have the same genes c. have the same alleles d. are inherited together This plant is _____ for pod color and ______ for seed shape. a. dominant/recessive b. homozygous/heterozygous c. recessive/dominant d. heterozygous/homozygous

Explanation / Answer

45)The answer is a. Allele is nothing but the alternative form of a gene representing the same trait.

46) The answer is C. In incomplete dominance, intermediate trait is observed due to incomplete inheritance of one of the allele.

47) The answer is A. Heterozygous has one dominant allele and one recessive allele (Cc).

48) The answer is B. Phenotype is the external appearance of an organism whereas genotype is it's genetic makeup.

49) The answer is B. Homologous chromosomes have the same gene at same loci but have different alleles.

50) The answer is D. The color is due to Tt gene which heterozygous and seed shape is given by dd gene which is homozygous.
